We used linear regression and phylogenetic analyses to assess associations between wood nutrients and tree height and analysis of variance to assess how wood nutrients vary across vegetation types. Alien trees had lower wood nutrient concentrations than many native trees, and nutrient concentrations, ...
Productivity and cost of conventional understory biomass harvesting systems. Conventional harvesting equipment was tested for removing forest understory biomass (energywood) for use as fuel. Two types of systems were tested - a one-pass system and a two-pass system. In the one-pass system, the ...
